          <p>The Interactive Satellite Viewer does not support the browser you are curently using. iSat requires a browser with WebGL graphics. For the optimal experience, we recommend updating to the most recent version of <a href="https://www.google.com/intl/en/chrome/browser/">Chrome</a> or <a href="http://www.mozilla.org/en-US/firefox/new/">Firefox</a>.</p>

          <p>Below, we present a 2D representation instead of the interactive 3D view you would get with WebGL. You can hover over a satellite to reveal its name and show an orbit trace.</p>
